Active Speed Sensors - RF

Active, or amplified sensors with digital output offer a low cost solution for interfacing directly to data acquisition systems. These sensors integrate a preamplifier/signal conditioner within the sensor housing and offer the advantages of excellent noise immunity and greater transmission capability.

Input power supply requirements cover the most popular ranges for both commercial and industrial use. The output frequency of these sensors has a square pulse waveform (digital) that directly relates to the number of turbine blades, gear teeth, etc. that have been sensed. These pulses, in turn, can be correlated to determine flow rate, RPM, or velocity.

In addition to the standard models shown above, active VR and RF speed sensors are available in custom lengths, diameters, configurations, and mounting threads. Custom operating specifications (output options, etc.) are available, as well as options such as pigtail leads or NPT threading. Additional sensor customization options

We provide custom sensors on a regular basis and are happy to help develop a solution for your application, or a replacement sensor for an existing application. Please contact our engineering department at eng@motionsensors.com or 252-331-2080 to discuss your application requirements.
